Look down where the binding posts are. You will see a series of knobs that will allow you to control hi's low's and mids. Carver made a speaker control box which was an outboard feature. He later incorporated then into the platinum speakers and called them Mark IV's He also did the same with the Silver Series.

So, is this is the only difference? No difference in the crossover, ribbon design, or the woofers? What does a Carver Speaker Control Box run these days, and will it be impossible to find? The reason I ask is because I may have found a seller of Platinums, but I don't believe he's got the Mark IVs or the control box. What are regular Platinums in fair/good condition worth on the market in comparison to Mark IVs?

the controls on the Mark IV's are the only ones I now of. I bought a box for my Caver Original Amazings. I had had a rewire and binding post replacement on my speakers and the difference was so terrific that the box didn't make much difference. It also has holography on it but my preamp already had that. I sold it. I would definately take the Mark IV's if it ere me. They usually go for 1600 0r more on ebay. The regular Plats a little less than that. You really have to keep your eye on ebay under Carver. Keep all Carver Speakers on your watch list. By the way i'm Canadian and with the difference in money and shipping hst at the border and brokerage fees I'm screwed. I just keep on improving my old Original Amazings If you get these things look into the rewire and binding post replacement. The original stuff is real shit.

The control box shows up on ePay from time to time, usually goes for $200.00 to $250.00. I have to agree with Tah, upgrading the chassis wire and binding posts is a must do.

Ditto buying the platinums. The MarkIV's just has that little adjustment panel. you don't need it. I would upgrade all of the different Models. The wiring was the same in all three models(and the posts too) Just curious ,what do you have to pay for the straight Platinum speaker? Art
